Connecting AC Power to a QFX3008-I Interconnect Device with Single-Phase Wiring Trays

A QFX3008-I Interconnect device is configured with six AC power supplies and two wiring trays.

Caution: Mixing different types of wiring trays in the same chassis is not a supported configuration.

Caution: To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the QFX3008-I Interconnect device must be adequately grounded before it is connected to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the QFX3008-I Interconnect device to connect to earth ground. For instructions on connecting a QFX3008-I Interconnect device to ground using a separate grounding conductor, see Connecting Earth Ground to a QFX3008-I Interconnect Device. A QFX3008-I Interconnect device receives additional grounding when you plug the power supply in the device into a grounded AC power outlet by using the AC power cord appropriate for your geographical location. See AC Power Cord Specifications for a QFX3008-I Interconnect Device with Single-Phase Wiring Trays.

Note: Each wiring tray AC appliance inlet must be connected to a dedicated AC power source outlet.

Before you begin to connect power to the device:

• Ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
• Install power supplies in the device. See Installing an AC Power Supply in a QFX3008-I Interconnect Device.
• Install single-phase wiring trays in the device. See Installing a Wiring Tray in a QFX3008-I Interconnect Device.

Ensure that you have the following parts and tools available to connect power to the device:

• Electrostatic discharge (ESD) grounding strap
• Power cords appropriate for your geographical location. See AC Power Cord Specifications for a QFX3008-I Interconnect Device with Single-Phase Wiring Trays.

Warning: Ensure that the power cords do not block access to device components or drape where people can trip on them.

To connect AC power to a QFX3008-I Interconnect device with single-phase wiring trays (see Figure 1:

1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
2. Ensure that the wiring tray is fully inserted and latched securely in the chassis. See Installing a Wiring Tray in a QFX3008-I Interconnect Device.
3. Set the switch, which is near the top of the wiring tray faceplate, to the OFF (O) position.
4. Locate the power cord or cords shipped with the device; the cords have plugs appropriate for your geographical location.
5. Insert the coupler end of the power cord into the AC appliance inlet on the wiring tray faceplate. See Figure 1.

6. If the AC power source outlet has a power device, set it to the OFF (0) position.
7. Insert the power cord plug into an AC power source outlet.
8. Repeat Step 5 through Step 7 for each AC appliance inlet on the wiring tray faceplate.
9. If the AC power source outlet has a power device, set it to the ON (|) position.
10. Verify that each LED on the wiring tray faceplate is lit solid green. Verify that each LED on the power supply faceplate is lit solid green.
